I miss the CVG hub! I flew in and out of there Christmas last year and it is so different than the hub days--it was a little sad. I would 1000x much rather have connected there than ATL.
it was non stop according to the monitor at gate B5. Not sure if it was a once weekly or summer seasonal service though. This particular summer day also had nonstop flights arriving from Munich, Paris, and Zurich (all three hadn't yet arrived during my visit, but gates B9, B7, and B6 respectively had monitors displaying the flights). The 777-200 seen in this video was arriving from London-Gatwick at gate B10.
I was working for Comair inside Concourse C at the time. The SABENA flight was a nonstop, both ways! During the fall & winter, the flight was operated by either an Airbus A340 or an MD-11, but once the weather warmed up, here came the Boeing 747-300!
